    Area of Science:

    • Medical Physics
    • Radiation Oncology

    Background:

    • Skull radiotherapy presents challenges in achieving uniform dose distribution.
    • Existing methods may lead to under- or over-dosing critical structures.

    Purpose of the Study:

    • To design and implement a universal compensator for megavoltage cobalt-60 radiotherapy of the skull.
    • To improve dose conformity and reduce radiation-induced toxicity.

    Main Methods:

    • Construction of a custom universal compensator tailored for skull geometry.
    • Application of the compensator in clinical megavoltage cobalt-60 radiotherapy protocols.

    Main Results:

    • The universal compensator enabled more homogeneous dose delivery to the skull.
    • Clinical application demonstrated feasibility and improved dose distribution.

    Conclusions:

    • A universal compensator is effective for optimizing skull radiotherapy with cobalt-60.
    • This innovation offers a practical solution for enhancing radiation therapy precision in neuro-oncology.
